Oil pan to block bolts are 10nm torque, with both Bentley and BMW instructions saying to tighten transmission bellhousing bolts last.

When I did mine, factory/Bentley recommended 3mm wide by 2mm high of RTV sealant. 2mm seemed a bit much, I think I did around 1mm high (and 3mm wide). Made sure the block surface was oil free before applying the sealant. Used Permatex Ultra Copper RTV sealant.

Used a BMW oil pan gasket.

No leaks after 15K miles.
